Abstract
Provided is a battery having a higher charge-discharge capacity density than conventional batteries, and exhibiting excellent charge-discharge cycle properties and charge-discharge efficiency. This battery (1) is provided with a positive electrode (2), a negative electrode (3), and an electrolyte solution which lies between the positive electrode (2) and the negative electrode (3) and which comprises an electrolyte, the positive electrode (2) containing rubeanic acid or a rubeanic acid derivative as an active material, and the molar concentration of the electrolyte in the electrolytic solution being greater than 1.0 mol/L. This battery (1) has a large volume of anions originating from the electrolyte, and rubeanic acid or a rubeanic acid derivative can be used from the oxidant to reduced form thereof, thus it is possible to obtain a higher charge-discharge capacity density than conventional batteries, excellent charge-discharge cycle properties and excellent charge-discharge efficiency.
